FIELD OF THE INVENTION

The present application relates to an oral cavity cleaning tool, and in particular, to an interdental brush used for cleaning a tooth clearance.

BACKGROUND OF THE INVENTION

Age increasing, pathology, and the like easily cause gum recession and enlarged tooth clearance, and extremely easily cause food remains. If the food remains fails to be timely cleaned, in one aspect, bad breath is generated, and in the other aspect, various dental diseases, oral cavity diseases, and especially periodontitis easily occur.

In view of this situation, currently, various interdental brushes are developed in the market for users to choose. Although products of various structures and different specifications exist in the existing market, the existing products generally have some defects. In the prior art, an interdental brush is divided into a plastic handler portion and a brush working portion, where diameter of the working portion is usually between 0.8 mm to 1.2 mm and length of the working portion is about 13 mm, and the working portion is a brush structure in which polymer fiber is attached to a metal wire; and the brush working portion is fastened at a front end of the plastic handler, and the brush working portion is exposed outside of the handler. The interdental brush needs to enter tooth clearances of different locations at different angles. However, the diameter of the working portion of the interdental brush is only about 1 mm, and the length of the working portion of the interdental brush reaches 13 mm, so force delivery is poor. It is difficult for the interdental brush of the prior art to be aligned to the tooth clearance in deep oral cavity, so by using the interdental brush of the prior art, the metal wire is bended, or the metal wire stabs gum and causes the gum bleeds, so the interdental brush is inconvenient to use.

To avoid the gum being stabbed by the metal wire, in the interdental brush of the prior art, there is also an interdental brush made of soft polymer material. Although the head of the interdental brush becomes soft, which reduces harm to the gum, strength of the interdental brush is low, so bending deformation is easily caused and it is difficult for the interdental brush to be aligned the tooth clearance and pushed into the tooth clearance; therefore, the tooth clearance is hard to be cleaned.

Generally, there are problems during use of the interdental brush of the prior art, for example, it is difficult to observe a tooth clearance and align the tooth clearance, the interdental brush easily bends and is hard to insert into the tooth clearance, which easily cause an unexpected gum injury; and when the interdental brush of the prior art is used to clean a tooth clearance between molars, especially a tooth clearance between a third molar and a second molar, or a tooth clearance between a second molar and a first molar, or a tooth clearance between a first molar and a second molar, there are the following defects: the light is dim, it is difficult to observe the tooth clearance, the interdental brush is difficult to enter the tooth clearance, and the interdental brush may easily stab the gum. In addition, when there is no external lighting, a user can perform operations only by feed; therefore, it is very easy to stab gum tissue.

SUMMARY

An objective of the present application is to provide a new type interdental brush, for which a tooth clearance is easily observed, the interdental brush can easily enter the tooth clearance, force delivery is good, the interdental brush can move back and force in the tooth clearance, the interdental brush can easily clean the tooth clearance, and will not stab gum.

One core of the technical solutions provided in the present application is: making a working part of the interdental brush automatically bend for easily aligning a tooth clearance; and reducing a distance that the working part of the interdental brush from an outlet of a delivery component to the tooth clearance, where a shorter distance indicates a good controllability of the interdental brush. The objective of the present application is implemented by:

a built-in interdental brush, where the built-in interdental brush includes an interdental brush 1 and a delivery component 2, and the interdental brush 1 may be movably built in a bended tube 21-1 of a front end of the delivery component 2, where

A: the delivery component 2 includes a guide head 21, a sliding mechanism 22, and a housing 23, where the guide head 21 is disposed on the front end 2-1 of the delivery component 2, and the guide head 21 includes the bended tube 21-1, and an outlet 21-2 of the bended tube 21-1 is disposed at an end 21-3 of the guide head 21;

B: the interdental brush 1 includes a working part 11 with fiber or a protrusion 11-1 and a connector 12, where the working part 11 is disposed at a front end of the connector 12; and

C: the interdental brush 1 is installed in the bended tube 21-1, the working part 11 of the interdental brush can slide in the bended tube 21-1, and the connector 12 of the interdental brush is installed on the sliding mechanism 22 of the delivery component 2; a movement of the sliding mechanism 22 can drive the working part 11 of the interdental brush slide in the bended tube 21-1; and the sliding mechanism 22 is driven to make the working part 11 of the interdental brush extend from the outlet 21-2 of the bended tube at the end of the guide head.

Further, the interdental brush 1 is of a linear type and is made of elastic material. After elastic deformation of the linear type interdental brush 1, the linear type interdental brush 1 can be installed in the bended tube 21-1, and after the working part 11 of the linear type interdental brush 1 extends from the bended tube 21-1, the working part 11 of the interdental brush can be returned or basically returned to the linear type.

The elastic material is selected from elastic polymer material or elastic metallic material. For example, the fiber or the protrusion 11-1 of the working part 11 of the interdental brush is made of elastic polymer material, and the connector 12 is made of elastic metallic material. By using an injection molding process in a metal mold, the connector 12 made of the elastic metallic material and the fiber or the protrusion 11-1 made of elastic polymer material are formed into a whole, so as to form the interdental brush 1. Therefore, the interdental brush of a composite structure not only ensure softness of the working part 11 of the interdental brush, but also keep flexible and appropriate stiffness of the whole interdental brush, and force delivery of the interdental brush is good.

The interdental brush 1 further includes a smooth guide head 11-2, and the smooth guide head 11-2 is disposed at a front end of the working part 11 of the interdental brush. Disposing the smooth guide head 11-2 at the header of the interdental brush may effectively prevent the gum from being stabbed.

The smooth guide head 11-2 is cone-shaped or bullet shaped.

The fiber or the protrusion 11-1 of the working part 11 of the interdental brush is a protrusion formed by a thread structure, or a vane-type protrusion, or a fibrous protrusion, or the like.

The sliding mechanism 22 includes an interdental brush connecting mechanism 22-1 and a sliding block 22-2, where the interdental brush connecting mechanism 22-1 is disposed on the sliding block 22-2; and the connector 12 of the interdental brush is detachably connected to the interdental brush connecting mechanism 22-1, the sliding block (22-2) can be pushed and pulled to drive the interdental brush 1 to perform a reciprocating movement in the bended tube 21-1, so as to make the working part 11 of the interdental brush extend from or withdraw to the outlet 21-2 of the bended tube at the end of the guide head. The interdental brush 1 is detachably installed in the bended tube 21-1 of the delivery component 2 and is connected to the sliding mechanism 22, so that the interdental brush 1 may be easily replaced.

A mode of the connection between the connector 12 of the interdental brush 1 and the interdental brush connecting mechanism 22-1 of the sliding mechanism 22 is a concave-convex-fit connection mode, or a threaded connection mode, or an interference-fit connection mode, or the like.

The sliding mechanism 22 further includes a driving spring 22-2 that can push the sliding mechanism 22 to move forward, where one end of the driving spring 22-2 is connected to the sliding mechanism 22 and the other end is connected to the housing 23. The driving spring 22-2 can apply a moderate size and uniform push force to the interdental brush, so as to prevent the gum from being stabbed.

Generally, the push force applied by the driving spring 22-2 to the interdental brush 1 is smaller than 100 g. The push force applied by the driving spring 22-2 to the interdental brush 1 should not harm the gum.

A built-in interdental brush of the present application uses a structure in which the interdental brush 1 is built in the bended tube 21-1 of the guide head 21 of the delivery component 2, after the working part 11 of the interdental brush 1 made of elastic material is aligned to a tooth clearance, the sliding mechanism 22 on the delivery component 2 is pushed to drive the working part 11 of the interdental brush 1 automatically bend along curvature of the bended tube 21-1, the working part 11 of the interdental brush 1 is aligned to the tooth clearance and pushed into the tooth clearance, and by pushing and pulling the sliding block 22-2 on the sliding mechanism 22 of the delivery component 2, the working part 11 of the interdental brush moves back and forth in the tooth clearance to clean the tooth clearance. Because the delivery component 2 has good stiffness, after the outlet 21-2 of the bended tube of the guide head of the delivery component is aligned to the tooth clearance, the pushed out working part of the interdental brush 1 directly enters the tooth clearance, and because the outlet 21-2 of the bended tube of the guide head of the delivery component is almost close to the tooth clearance, the working part 11 of the interdental brush is hard to be bended, force delivery of the interdental brush 1 is significantly improved and controllability of the interdental brush 1 is improved, thereby avoiding that, when the interdental brush of the prior art is used to clean a tooth clearance between molars, the interdental brush easily bends and hurts the gum. Especially after a lighting system 24 and an observation system 25 are added to the built-in interdental brush of the prior art, a lighting condition in an oral cavity is improved, the clearance between molars may be clearly observed, and a process that the interdental brush enters the tooth clearance is directly observed, which is convenient for cleaning and avoids an accidental injury to the gum.

Because the delivery component 2 has good stiffness, after the outlet 21-2 of the bended tube of the guide head of the delivery component is aligned to the tooth clearance, the pushed out working part of the interdental brush 1 directly enters the tooth clearance, and because the outlet 21-2 of the bended tube of the guide head of the delivery component is almost close to the tooth clearance, the working part 11 of the interdental brush is hard to be bended, force delivery of the interdental brush 1 is significantly improved and controllability of the interdental brush 1 is improved.

In addition, the end 21-3 of the delivery component 2 is a smooth plane with certain strength, so at the same time when the end 21-3 acts as a stress-bearing point that plays a stress-bearing surface function when the working part 11 of the interdental brush 1 enters the tooth clearance, because of a smooth surface contact pattern, no sharp pressure will caused on the gum or a surface of the gum will not be injured, which ensures comfortableness of the human body when the working part 11 of the interdental brush 1 is pushed by the sliding block 22-2. In addition, the guide head 11-2 of the end of the working part 11 of the interdental brush 1 has a smooth cone-shaped curved surface, so when the working part 11 of the interdental brush 1 enters the tooth clearance, the working part 11 is not affected by slight position deviation, so the working part 11 enters the tooth clearance easily and does not hurt surrounding gum when entering the tooth clearance.

Because the sliding block 22-2 of the sliding mechanism 22 is a mechanism which may move back and forth, in a cleaning process, the interdental brush 1 may be driven to move back and forth in the tooth clearance by sliding the sliding block 22-2 back and forth to finish cleaning the tooth clearance successfully.
